3 Claims.

The present invention relates to a brush provided with spraying means soconstructed as to provide a means for adequately and satisfactorilycleaning type or the like.

More specifically, the invention pertains to a bristle brush equippedwith a chemical solution container, the latter provided with a bulbequipped spray nozzle conveniently arranged for applyin the solution tothe surface to be cleaned, the latter result being accomplished throughproper use of the bristles.

In carrying out the prefer-red principles of construction a solutioncontaining tank, equipped with a bulb and spray nozzle, is mounted onthe back of the brush by way of a simple housing, the completeconstruction serving to provide appropriate means for expeditiouslyapplying the chemicals and thereafter brushing and removing same toaccomplish the desired results.

Novelty is predicated upon the simple housing which is attached to theback of the brush and which encloses the solution container, the latterbeing accessible for convenient replenishment of the solution and beingprovided at one end with a bulb equipped spray nozzle.

Needless to say I am aware that solution applying bristle brushes arenot new. It follows, therefore, that in devising the. present inventionI provide a structure which is believed to be possessed of refinementsand improvements not heretofore utilized in prior devices.

Other objects, features and advantages of the invention will becomemore, readily apparent from the followin description and theaccompanying .illustrative drawings.

In the drawings, wherein like numerals are employed to designate likeparts throughout the views:

Figure 1 is a perspective view of a type scrubbing and cleaning brushconstructed in accordance with the principles of thepresent invention.

Figure 2 is a perspective view, this on a smaller scale showing thestructure seen in Figure 1 with the filler neck cap removed and furthershowing the step of filling the tank or container from a reserve supplycan and utilizing a funnel for such purpose.

Figure 3 is a perspective View showing the manner in which the brush isused and also the manner in which the spray nozzle is brought into p y.

Figure 4 is a, top plan view of the construction seen in Figure 1.

Figure 5 is a view with the brush in elevation 55 2 and the other partsprimarily in vertical section.

Figure 6 is a sectional view of the hand bulb equipped nozzle means.

Referring now to the drawings by distinguishing reference numerals, itwill be seenxthat the brush, which is somewhat conventional, is denotedby the numeral 8. The back of the brush is denoted at 9 and the bristlesat It. The casin'g corresponds in outline to the back of the brush, andis denoted by the numeral ll, and this fits over and around the back ofthe brush, being held in place by lugs or equivalent detents #2. Thiscasing, whichconstitutes the-aforementioned housing, is provided withIan openin 13 at one end and another openin M at the central portion ofthe top.

The casing l I is such as to accommodate and satisfactorily maintain inplace a container or reservoir i5. This part is in the form of asocalled rectangular tank and is confined in the position shown inFigure 5. Reference being had to the latter figure, it-will be notedthat the filler neck l6 projects through and beyond the hole or openingM to expose the removable screw-cap IT.

The dischargeend [8 of the tank is constructed to accommodate the spraynozzle means, generally denoted by the reference numeral l9 (seeFigurec). Referencebeing had to the latter figure, it will be seen thatsaid means comprises an elongated suction-type solution withdrawal anddischarge tube 20, the latter having a rubber intake nipple 2| on theinner or intake end thereof. The outer end 22 of the tube is closed andinwardly of this is a lateral branch i3 provided with a squeeze-typebulb :24- In line with the branch 23 andformedin the body of the tubeisa restricted discharge orifice 25 through which the chemicalsolution orother liquid 26 is forcibly sprayed in the manner illustrated in Figure3. The dischargeend l 8 of the tank is provided with a sleeve-likefitting. or neck 21 which extends hr ueh and beyond the aiorem ntionening 63 (see Figure 5), said fitting being screwthreaded to accommodatea screw-cap 28. The screw-cap Z8 is mounted on the aforementioned tube20 and screws on the neck 21, said cap containing appropriate pipingelements 29 and 30 afiording the desired fluid tight connection betweenthe fitting, cap, and tube.

In practice, the brush is employed as illustrated in Figure 3. That isto say, the brush is operated in one hand and the bulb 24 is pressedwith the other hand, thus spraying the chemical cleaning solution, orother liquid preparation on the surface to be cleaned. By applying ordepositing the solution on the surface as wanted, the brush may beconveniently manipulated according to custom and the needs andrequirements of the user. 1

In Figure 2, I have shown the manner of replenishing the supply ofliquid in the tank whenever necessary or desired. To accomplish this,the screw-cap I1 is removed, the funnel is placed in the filler neck andthe needed fiuid is poured 1 from a can B into the funnel for deliveryinto the tank Hi.

The essence of the invention, it is believed, resides in the provisionof a tank, constituting a liquid containing reservoir, the same being somade that it may be installed between the back of a brush and a casingcarried by the back, said tank having, at any suitable point, a fillerneck and a closing gap for the filler neck. Primarily, however, noveltyresides in the provision of the spigot or pump equipped nozzle means onthe left hand end of the tank protruding beyond the tank and alsoadapted to protrude beyond the casing on the brush. The means is novelin that the tube 20 is fastened in the discharge neck 21 and has itsinner end projecting to a point within the vicinity of the liquid in thetank, said inner end carrying the flexible piece of hose 2| whichprovides an economical type of a nipple. This nipple, incidentally,prevents liquid from running out under normal circumstances but affordssufficient of a passage, like the opening in a nursing nipple, that whensuction is applied by the bulb 24, liquid is drawn through the nippleand into the discharge tube 20. Sumcient liquid is trapped in this tubeand also a certain amount of it is drawn up into the bulb 24. It followsthat when the bulb 24 is squeezed there is sufficient liquid in the bulband tube combined to force and spray some of the liquid out through theorifice 25. Of course, a certain amount of liquid will be forced backthrough the tube 20 to the right and out through the nipple and into thecontainer again. However, and as a general proposition suflicient liquidis thus loaded in the tube to provide the desired alternate intake anddischarge results.

While in the foregoing there has been shown and described the preferredembodiment of this invention it is to be understood that minor changesin the details of construction, combination and arrangement of the partsmay be resorted to without departing from the spirit and scope of theinvention as claimed.

What I claim is:

1. In a structure of the class described, a liquid container providedwith a discharge fitting at one end, a screw-cap on said fitting, aliquid dispensing tube mounted in said fitting and held removably inplace by said screw-cap, a nipple on the inner end of said tube andlocated in the body of the container, said tube being provided with adischarge orifice and a squeeze-type bulb 4 mounted on said tube in amanner to force liquid through the orifice when squeezed and to suckliquid from the container into said tube when it is released andconsequently inflated.

2. A liquid container and dispenser unit for use in connection with atype scrubbing brush wherein the brush embodies a bristle equipped backand a casing carried by the back; a tank adapted to be situated in thespace between the brush back and casing, said tank being provided with afiller neck and a screw cap for closing same, said tank being furtherprovided at one end with a discharge neck, a dispensing tube having itsintermediate portion disposed in said discharge neck, a closing cap onthe intermediate portion of said tube for attaching same detachably tothe discharge neck, a short length of flexible hose attached to theintake end of said tube and providing a nipple, said nipple beingadapted to operate in liquid within the confines of said tank, theopposite outer end of said tube being provided with a liquid dischargeopening, and a hand operated suction bulb on the outer end of the tubein approximate alignment with said discharge opening.

3. As a new article of manufacture and as a component part of spraynozzle means of the class described, an elongated rigid tube open at oneend and closed at the opposite end, the last named end being providedwith a liquid discharge orifice for liquid spraying and being furtherprovided with a branch pipe laterally disposed and lined up with saidorifice, a hand squeezed suction bulb on said branch, a screw capcarried by the intermediate portion of said tube for attaching same to adischarge neck carried by a liquid containing tank, and a short lengthof rubber hose connected to the inner open end of said tube, said hoseconstituting a flexible nipple.
